UPDATE Jan. 12, 6:13 p.m. – After nearly 10 hours of continuous lava fountaining, Episode 40 of the ongoing Halemaʻumaʻu eruption abruptly ended at 6:04 p.m. on Jan. 12. Episode 40 began at 8:22 a.m. on Monday, Jan. 12. The Hawaiʻi Volcano Observatory will continue to closely monitor Kīlauea and will issue additional notices as activity warrants.

From USGS Hawaiian Volcano Observatory livestreaming V2cam, a plume-like fountain erupted from the north vent during episode 24 on June 4–5, 2025, creating an elegant arc. With a maximum fountain height of 364 meters (1194 feet), this was the highest fountain observed up until that point. USGS photo.

Mount Etna is Europe’s most active volcano and the continent’s largest. It attracts hikers and backpackers to its slopes, while less adventurous tourists can take it in from a distance, most stunningly from the Ionian Sea.

The Kīlauea summit has inflated by 23 microradians since the end of Episode 39 on Christmas Eve, Dec. 24, 2025, including an increase of at least 1.3 microradians within the past 24 hours. Slight deflation happened at about 5 a.m. today when the south vent overflowed, then increased somewhat at 7 a.m. when both vents became active.

Kīlauea summit region shook for 5 hours Nov. 14 that year as magma made a path to the surface. The eruption began at 8:08 p.m. as a series of small lava fountains on the south wall of Kīlauea Iki Crater, east of Kaluapele — the summit caldera of Kīlauea. Gradually, during the next day, eruptive activity became focused at one vent.
